New LLM approach enhances simultaneous speech translation without architectural changes

Researchers have developed a novel data-driven approach called CSSEL-P2P to improve simultaneous speech translation (SimulST) in decoder-only LLM systems. This method utilizes fixed-length chunks for cumulative streaming decoding and teacher-labeled prefix-to-prefix targets for fine-tuning, aiming to overcome latency and reordering challenges without requiring architectural modifications. Evaluations showed CSSEL-P2P achieved a +1.54 COMETKiwi improvement over a baseline at comparable latency, demonstrating its effectiveness for SimulST. AI

IMPACT This research offers a more robust method for achieving low-latency speech translation with LLMs, potentially improving real-time communication tools.

Do LLMs Need Architectural Changes for Simultaneous Speech Translation? A Prefix-to-Prefix Data Driven Approach

Simultaneous speech translation (SimulST) requires incremental translation under strict latency constraints, yet remains challenging for decoder-only LLM systems due to limited context and cross-lingual reordering. Recent approaches often introduce architectural changes or explic…
